If a text doesn't say delivered on my iPhone, did they still receive it?

If a text doesn't say delivered on my iPhone, did they still receive it?

Most of the time

Usually if it doesn't say delivered maybe the other person just has a slow connection to receive it, but they do end up getting it sooner or later. If your send button turns green but your conversation is in blue that means either you or the other person lost connection to use iMessage.

Hope that helps.
